What is an SSD?

A solid state drive (SSD) is a storage device used in computers that uses flash memory to store data that is accessed digitally.

An SSD serves as your computer's long-term memory. It stores files even when your device is turned off and works alongside your system's RAM and processor to access and use data, such as your documents, programs, operating system, and even music and games.

Since SSDs have no moving parts to them, they are less prone to failure. Upgrading to one will greatly improve the speed of your computer or application and make it more resilient.

There are a few types of SSDs currently on the market, and we will explore each of them in a later section.

How an SSD Works

How To Use An SSD

An SSD works by storing data and files in your computer for long-term use, even when the computer loses power or is turned off.

SSDs use a grid of electrical cells to send and receive data quickly. The grids are separated into different sections called pages, where the data is stored. The pages then form blocks.

SSDs cannot overwrite data in individual pages, they can only write data to empty pages in a block. When pages in a block are unused, the SSD will commit the entire block's worth of data to memory, erase the entire block, and then it will re-commit the data from memory back to the block while leaving any unused pages blank.

When a block is erased, the data isn't completely gone, but data can still be securely deleted on an SSD.

However, as expected, your SSD will become slower over time with the more data that is stored on it.

SSD Terms to Know

We've put together a helpful glossary of key terms that you will encounter as you learn more about SSDs.

  • Interface - this is where two independent systems communicate. In an SSD, it is a connector that plugs the SSD into the motherboard and power supply. Common SSD interfaces include SATA III and NVMe.

  • IOPS (Input/Output Per Second) - a measurement of performance for SSDs and it represents how quickly a given storage device can read and write commands in every second.

  • NAND (Negative AND) - the technology that creates flash memory.

  • NVMe (Non-Volatile Memory Express) - a standard hardware interface for SSDs that uses the PCI Express (PCIe) bus.

  • QLC (Quad-Level Cell) - contains four bits per cell, allowing for four times the capacity of SLC flash memory.

  • Read - accessing a piece of data from memory or a storage drive.

  • SATA (Serial Advanced Technology Attachment) - an interface that connects a storage drive to a motherboard.

  • TLC (Triple-Level Cell) - a type of NAND flash memory that stores three bits of data per cell. Older options of FLASH memory include SLC (single-level cells) and MLC (multi-level cells).

  • Wear Leveling - a feature that ensures all NAND cells on a flash-based storage device are used equally to prolong the life of the SSD.

  • Work Load - the percent of time that a drive is "read" versus the amount of time the SSD will be "write".

  • Write - saving a piece of data to a storage drive.

The Benefits of Using an SSD

There are many benefits to using an SSD in your application. We explore just a few of those benefits in this section.


SSDs rely on less power to operate compared to hard disk drives (HDDs), making them much more energy efficient. SSDs are a much more attractive option for applications such as PCs where battery longevity is important.

Long Product Lifetimes

SSDs have a long product lifetime compared to similar storage devices. In fact, they have an average mean time before failure of 1.5 million hours.

Fast Performance

SSDs can handle data at the super high speeds that are necessary in today's business environment, especially when running programs that need to access large amounts of data.

Smooth and Silent Operation

Since they work with flash technology, the operation of SSDs is smooth and silent, making for a calm and efficient work environment.

Different Classes of SSDs

Solid State Drives

There are few types of SSD classes, as they are extremely versatile and can be used in many different applications. We will explore a few in this section.

  • Client SSDs - SSDs that are associated with client desktop, notebook, tablet, and smartphone applications, and is mostly used for storing operating systems and user data.

  • Consumer SSDs - SSDs that are designed to be inexpensive and not intended for use in OEM or IT applications.

  • Enterprise/Data Center SSDs - originally developed to replace hard drives, enterprise SSDs are mostly found in enterprise-level data center applications. Many of these data centers that once relied on HDDs now rely on SSDs because they provide a storage solution that will increase performance and efficiency, as well as lower operating costs.

Types of SSD Interfaces

Solid state drives are typically available in a few different interfaces, such as PCIe, SATA, and SAS. Each of these interfaces have evolved greatly over the years.

  • PCIe - the fastest and largest interface available on the market today, these drives are equipped with high-performance memory. These drives are ideal for data centers, hosting companies, computing centers, server farms, and more.

  • SATA - these drives replaced the previous PATA drives as they are the faster and more efficient memory option.

  • SAS - these drives are ideal for high-performance comuting environments with their high throughput and advanced control features.

What to Consider Before Purchasing an SSD


Many factors need to be taken into consideration before selecting and purchasing an SSD for use in your project or application. We explore a few of the key factors in this section.


SATA drives are typically much slower than NVMe/PCIe drives, since they are serial connection as opposed to the faster parallel PCIe bus.

In fact, NVMe SSDs combined with PCIe connection result in faster rewrite speeds than SATA SSDs.


The endurance of an SSD ultimately measures how long the SSD will operate, and it should not be overlooked when purchasing an SSD, especially for larger-scale applications such as data or hosting centers.

Endurance of SSDs vary greatly, and it depends on which type of SSD you end up choosing.

This is where drive writes per day (DWPD) come into play.

Drive Writes Per Day Definition

For example, let's say your SSD is 128GB and has a warranty time of 5 years. This means that you can write 128GB into the drive every day for the next 5 years.

As mentioned in an early section, SSDs have no moving parts, which it means they don't wear out as easily as an HDD, but unfortunately they don't last forever.

Form Factor

The form factors available for Micron SSDs are M.2 and 2.5-inch (SATA), and U.3 and E1.S (NVMe).

The 2.5-inch form factor is most used as a hard disk replacement for data applications, while the M.2 form factor is used for boot drive in laptops and PCs. The M.2 is tiny and thin, making it the ideal option for small applications.


The security capabilities of your SSD should never be overlooked. While SSDs are typically much more secure than HDDs, it is important that you understand your drive's encryption before purchasing.

Encryption is the process of obscuring data by running it through complex algorithms. A key is required to undo that process and restore the data after its lost.

An SSD that has encryption built into the hardware is called a Self-Encrypting Drive (SED). Micron offers a line of SEDs that support the Trusted Computing Group (TCG) Storage Security Class Opal and Enterprise protocols.

SSDs with hardware encryption offer increased security, maximized system performance, ease of use, and compliance among industry standards and government data security regulations.


Price is a big factor to keep in mind for anyone looking to purchase an SSD for their application, as prices of SSD vary from drive to drive.

Consumer drives are the least expensive, as they consist of the lowest capacities. Client SSDs are the "middle tier" in terms of pricing, as they are used in workplace applications. Lastly, enterprise SSDs are the most expensive because they consist of the best performance and highest endurance.

Micron offers 2 types of drives - PRO and MAX, with the PRO drives being a more economical option and the MAX drives consisting of longer endurance and longer warranties.

Storage Capacity

The capacity of a SSD is determined by the number of NAND chips it has per drive, the number of data cells on each chip, and the number of bits per cell.

Micron SSDs range in capacities from 240GB to 30TB, with the arrival of the new Micron 9400 NVMe SSD.

Here's a brief overview of what each SSD capacity means for your application:

  • 256GB-1TB - ideal for boot drive applications.

  • 2TB-7.6TB - ideal for storage arrays for large single drive storage.

  • 15TB-30TB - ideal for demanding data center workloads and larger capacities.

Power Consumption

Since SSDs consume significantly less power than HDDs, they are ideal for large data center applications.
